Ultrasonic components for perfect weld results

Ultrasonic welding technology is gaining in importance and is an increasingly frequent integral component in modern manufacturing processes. As an efficient, material-friendly and sustainable joining technique, it is ideally suited for joining thermoplastics or non-ferrous metals. Many mechanical engineering companies use this technology advantage when processing plastics or metals in customized machines. Robust and reliable ultrasonic components are a requirement for this. Linked together on a mechanical basis, the converter, booster, and sonotrode create an ultrasonic stack with a determined acoustic resonance. All ultrasonic components receive a 100% quality check: “Made in Germany”.

Converters

The ultrasonic converter converts high frequency electrical vibrations into a mechanical longitudinal vibration with a constant output amplitude.

Boosters

Strengthens the initial mechanical vibration of the ultrasonic converter for the plastic-dependent weld amplitude of the sonotrode.

Sonotrodes

The sonotrode gently directs mechanical vibrations into the plastic component on the basis of an even pattern of vibration.

Fixtures

Equipment for the holding and fixing of the plastic application. They form the counter-bearing for the weld force which is exerted by the sonotrode.

Anvils

The tooling profiles of the anvils focus the energy and ensure the best seal quality during the sealing of film.

Advantages of Herrmann ultrasonic weld components

Generators, converters, ultrasonic sonotrodes – all of the ultrasonic components stand out with:

Robust designs for the prevention of costly manufacturing downtimes
Easy integration thanks to the modularity of the components
Short standstill times with the replacement of components
Tried and tested quality with long availability of spare parts

Individual application options of ultrasonic components

Ultrasonic welding is used in an exceptional variety of applications: From the automated ultrasonic welding machine to the special welding machine through to the packaging machine. In the world of mechanical engineering, there are individual spatial situations in which ultrasonic components have to be integrated. In this respect, Herrmann offers a variety of types for individual customer requirements. In addition to this, requisite customized specialist developments are also realized at high quality. The tried and tested ultrasonic technology has also been put to successful use in the proprietary ultrasonic welding machine, ultrasonic systems and hand-held ultrasonic welders for many years

Ultrasonic welding

The operating principle

The key function in the ultrasonic system is carried out by the dynamic and high performance ultrasonic generator, which constantly generates a high frequency electrical vibration. The conversion into a mechanical vibration takes place through the piezoelectric effect in the ultrasonic converter.
